I just ordered a Road Tech Conquest GPS unit and would like to know the best way to wire it up.
Any help will be appreciated.

 

You didn't mention what type bike you ride. The touring bikes have an extra "hot with switch" lead right behind the headlight or tap into the lighter wires.

 

If you are using the faring mount it is very easy. And excellent instructions are included with the unit. If you go with the handlebar mount things are a lot harder.

 

I have the Conquest GPS. Although it came complete with charging and mounting cradle I didn't know that at the time so I ordered an extra one. It comes with a 7 page instruction sheet and hardware to connect directly to the fuse panel under your left side cover even though it has an inline fuse holder with water proof rubber cap already attached. I chose to use this inline fuse and attach to auxillary plug under seat by battery with a pigtail connector for this plug. Either will work and is powered once the ignition is turned to run or Aux. It's up to you. The harness is ran under the tank to what ever spot you have the Cradle mounted. Since it is low amp rating (2 amp) I wouldn't have had any problems on my Road King using the spare ignition switched plug in the headlight nacelle but I have already used this for my radar detector. Very easy install really.

 

Sorry, 09 Ultra

 

I have a Garmin 750, I bought a hard-wire cable and tied it into the accessory/aux light switch behind the headlight on my Fatboy forks. Of course, the switch had not been wired so I had to run leads from the battery to the forks (running under the tank was fun). The GPS cable comes up by the risers and into my fork bag then out to my RamMount. If I am not using the GPS I can tuck the wire back into my fork bag.

 

I have a Garmin 2610 on my UC. I hard wired it thru the fairing into the back of the cigarette lighter. Works great.

 

Zumo 550, it is hard wired thru the fairing into the back of the cigarette lighter. Works great.

 

I have a Garmin iWay500 on my Classic. I hard wired it through the fairing into the back of the cigarette lighter. Works great.

 

I wired mine off the ACC switch using this diagram. It will stay on as long as the ignition switch is on. Note that power is not regulated by the ACC switch. Don's suggestion of tapping into the cig-lighter circuit, or any other switched by the ignition, will also work well.
